I know an equal number of RA and GA aircraft owners. Their motivations for ownership are the same. Having owned both for periods of years, the ownership costs were similar. There is a trend toward RA aircraft ownership at present because:
CASA medical limitations
Old GA aircraft just got much more expensive (last two years)
People with money want a modern machine with modern instruments
Fuel prices have risen
You can sell your GA plane for big $$ and buy RA (but someone must have bought the GA plane)
We found out the kids/grandkids don't want to fly with us anyway
There are very few friendly accessible GA training schools remaining
Having an autopilot (one on button for alt hold and wings level) must be a major safety benefit for those caught in IMC. BTW a friend flew for nearly 30 minutes in IMC on a six pack (instruments, not beer) with no IFR training and he survived. But his wife refused to ever get in a plane with him again.
Pilots refused to use enclosed cockpits. The sound of the engine, the wind on one side of their face, and so on were essential for good aircraft control (they said).
Saw on the news today a blue Foxbat made an emergency landing in Russian occupied territory. Seems it was doing air obs and should have stayed over Ukrainin territory. It threw a prop blade hence the landing. The pilot has been detained. This answered my wondering why the Ukrainians were not using Foxbats. Seems that are.
I just sold a BMW boxer that was 38 years old. I never changed the carby diaphragms in all that time. Basically the same ones in a Rotax have to be changed every five years. So the level of caution is quite high.
At each renewal CASA require me to do a heap of tests that my cardiologist says are not necessary. And he would not ask for them, but they insist, and cost a lot. Just for a class 2, and I fly RAA now, so only needed to enter controlled airspace.
